Short answer

Designers and project managers must move beyond purely technical specifications for BIM models and actively consider the project's specific context and stakeholder needs when defining graphical data requirements.

Evidence: Moderate effect

The way graphical data is specified in Building Information Modelling (BIM) is heavily influenced by project context, including its use, stage, and the actors involved, rather than purely technological considerations. This modelling research insight is drawn from a 2022 study published in Journal of Information Technology in Construction. Using Qualitative strategy employing a cross-sectional design and grounded theory approach., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers and project managers must move beyond purely technical specifications for BIM models and actively consider the project's specific context and stakeholder needs when defining graphical data requirements.

Contextual Factors Significantly Influence Graphical Data Specification in BIM Modelling

Journal of Information Technology in Construction · 2022

Key Findings

01Six main themes influence graphical data specification: model use, project stage, project actors, processes and objects definitions, graphical granularity, and model attribute.
02Contextual factors at industry and organizational levels, such as mandates, influence how practitioners specify information.
03Existing specification frameworks often focus on non-geometrical data, leaving graphical information specification subjective.

Application

Design takeaway

How to apply

When developing or specifying BIM models, create a detailed checklist that considers model use, project stage, key stakeholders, and desired level of detail for graphical elements.

Project actions

01When modelling for a specific purpose (e.g., structural analysis vs. client visualization), ensure your graphical specifications reflect that purpose.
02Consider the different roles (architect, engineer, client) and how their needs for graphical information might vary.

Method & Evidence

AimTo identify and analyze the concepts that influence the specification of graphical data in BIM-enabled projects.

MethodQualitative strategy employing a cross-sectional design and grounded theory approach.

ProcedureData collection and analysis were conducted in two stages using theoretical sampling, involving interviews and document analysis to explore concepts defining graphical data specification in EIRs.

ContextBuilding Information Modelling (BIM) projects, focusing on the specification of graphical data within Exchange Information Requirements (EIRs).

Variables

IV["Project context (e.g., model use, project stage, actors, industry mandates)"]

DV["Specification of graphical data (e.g., graphical granularity, model attribute definition)"]

CV["Technological standpoint of BIM literature"]

Strengths & Limitations

Strengths

+Addresses a gap in BIM research by focusing on graphical data specification.
+Employs a robust qualitative methodology (grounded theory) to explore complex concepts.

Limitations

A simplified IA might not have the complexity to fully explore all contextual factors mentioned. The study's focus on EIRs might be too specific for some project projects.

Reliability & validity

The study's reliance on qualitative data and grounded theory suggests findings are context-dependent. Reliability could be enhanced through triangulation of data sources and methods. Validity is strengthened by the iterative nature of theoretical sampling, allowing concepts to emerge from the data.

Think critically

To what extent can graphical data specification in BIM be fully automated, given the strong influence of contextual factors identified in this study?

Design Principles

"Digital modelling specifications must be adaptable to project-specific contextual factors."

This highlights that effective BIM modelling, a form of digital representation, is not solely about the software or technical specifications. It requires a deep understanding of the project's unique environment and the needs of its stakeholders to ensure accurate and useful graphical data.

What This Means for Your Design

How you draw or model things in a digital building plan depends a lot on who you are, what stage the project is in, and what rules your industry or company follows.

How to use in your project

1.If your project involves digital modelling or CAD, discuss how project context (e.g., target user, manufacturing constraints) influences your graphical specifications and choices.
2.Use this insight to justify why a particular level of detail or graphical representation was chosen for your model.

Paragraph starter

The specification of graphical data within digital modelling environments, such as Building Information Modelling (BIM), is significantly influenced by contextual factors. Research indicates that elements like the intended model use, the project's current stage, the involved stakeholders, and industry-specific practices play a crucial role in defining the required graphical granularity and attribute detail, moving beyond purely technological considerations (Murillo A. Piazzi et al., 2022).
